Comparison between Lichtenstein And Laparoscopic Totally Extraperitonial (TEP) Tension Free Mesh Repair of Inguinal Hernia.

To compare the outcome of the laparoscopic totally extra peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia. This study was conducted as a prospective comparative (Quasi experimental) study from January 2010 to December 2010 at Combined Military Hospital (CMH), Dhaka, Bangladesh. A total of 100 male patients aged 24 to 70 years who underwent laparoscopic totally extra-peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia were included in this study. Data of operating time, intraoperative and short-term postoperative complications, postoperative pain, postoperative hospital stay and return to normal activity were recorded and analyzed with SPSS program. Mean age of the patients was 51.39±15.099 years in OLMR group (Group A) and 47.10±9.338 years in Lap TEP group (Group B). Mean operating time was longer in Laparoscopic TEP group (Group B, 57.67±6.915 minutes) then open Lichtenstein mesh repair group (Group A, 50.56±6.292 minutes). Patient in the Lap TEP group (Group B) experienced less post operative pain, less post operative complications, shorter hospital stay and early return to normal activity then OLMR group (Group A). One patient (3.33%) in group B needed conversion to open Lichtenstein method. Two (6.66%) patients developed pneumoperitoneum in Group B (Lap TEP repair). Superficial wound infection developed in five (7.14%) patients in OLMR group (Group A) and two (6.66%) patients in Lap TEP group (Group B). In Laparoscopic TEP group (Group B) and Lichtenstein group (Group A), patients return to normal activity within on an average 07 and 11 days respectively. Laparoscopic totally extra peritoneal (TEP) mesh repair technique was associated with less post operative pain, less post operative complications, shorter hospital stay, faster recovery with early return to normal activity compared with Lichtenstein tension free mesh repair of inguinal hernia.
